In recent years, we have worked out a greenhouse mulberry, cowpea, celery multiple cropping pattern, three kinds of three incomes a year, with significant economic benefits. Cucumbers were planted before and after January 15, and planted at the end of February and early March. Harvested from the beginning of April to the end of June. The yield per mu was 3,200 kg and the per mu value was 5,100 yuan. The cowpeas were planted in rows between the cucumbers at the beginning of June, from early August to early September. Harvesting, yield 3000 kg per mu, production value of 4200 yuan; celery in mid-July planting seedlings, planting in late September, early December to early January next year harvest, mu yield 3500 kg, mu production value of 5600 yuan. The annual output value per mu is 14,900 yuan, after deducting the cost of 3,500 yuan, the net income per mu is 11,400 yuan. Cucumber selection of Jinchun 10, Jin Za 1 and other early-maturing low-temperature varieties. Greenhouses are covered with small arch shelters. Before planting, 2500 kg of organic fertilizer and 45-50 kg of compound fertilizer were used per acre. Planting small row spacing 0.5 meters, large row spacing 1.5 meters, spacing 25 cm. After planting the cover mulch, take a small arch shed and cover the grass curtains on the small shed at night. After the seedlings are slowed, the seedlings are slowly poured and the cultivator is properly cultivated. When the female flower is open, artificial pollination or bee pollination is performed around 9:00 am to increase the rate of pod formation. After sitting on the melon, timely fertilization, watering, combined with water application Shishui manure or urea. During the guava period, water is poured every 2 to 3 days. Phosphorus and potassium fertilizers are added appropriately, and foliar fertilizer such as potassium dihydrogen phosphate is sprayed. The main prevention and control of downy mildew in the early stage, pay attention to ventilation and humidity, and use chlorothalonil smoke agent to close the shed smoke or use powder dust control. Every 7 to 10 days after planting a living plant, the pesticide is sprayed to prevent diseases, and various agents are alternately used. Combined with disease-prevention spraying of 0.1% to 0.3% potassium dihydrogen phosphate solution, both plant resistance can be increased, potassium fertilizer can be added, plant growth can be adjusted, and the harvest period can be extended. Kidney bean selection Yang Yan 40, Xia Bao and other fine varieties. Row spacing is similar to that of cucumber, and full use of the cucumber's frame, to achieve a dual purpose. Seedlings have 2 true leaves when cultivating and weeding once. Seedling period every 10 to 15 days per acre with 20% of the amount of manure water plus 10 kg of urea. During the harvest period, each batch of soybean meal harvested was applied with 20% of manure water and 20 kg of compound fertilizer per acre, which increased water supply in the event of drought. Spraying potassium dihydrogen phosphate solution has obvious effect on improving the yield at the later stage. The growth period of cowpea covers the insect net, which can reduce pests and diseases. At the seedling stage, it is mainly used to control aphids and aphids, and it is mainly used to control rust, cabbage caterpillar and soybean meal in the scab stage. Celery cultivar with strong anti-stress, wide adaptability, and good commercial properties, such as Jinnan Real celery. 150 grams of seed per acre of Daejeon will be planted on the top of the ground in mid-July to cover the shade net. Seed soaking in cold water for 8-12 hours before sowing, remove and drain water, spread with fine soil or fine sand and spread water. When the temperature is low at the late seedling stage, appropriate water control and seedlings should be used. After harvesting, cowpeas timely cleaned up the leaves and rotted roots, planted 15 cm apart and planted water. After easing the seedlings, when the heart leaves begin to grow, they are poured with a small amount of water. At the same time, 5 kg of urea is applied per acre, and then the seedlings are planted in shallow meddles. When the leaves start to grow upright, and the underground root system occurs in large numbers, fertilization and watering are started. Spraying 50 mg/liter of gibberellic acid solution at a height of 30 cm, watering and fertilizing in time after spraying, spraying once more every 15 days to increase the yield of celery. To prevent celery from being hollow in boron, spray 0.3% to 0.5% borax solution. The disease of celery is mainly spot blotch. In the early stage of disease, 50% carbendazim WP can be used 500 times, or 50% Mancozeb WP can be 1000 times, or 1:0.5 : 200 Bordeaux spray to control, and strengthen. Ventilation reduces the humidity in the booth.
